How do we differentiate true believers from false ones?

In the parable of the two harlots in 1 Kings 3, we see a stark contrast between those who truly claim Christ and those who merely spew religious language. The genuine believer, like the woman who cared for her living child, demonstrates love and sacrifice for the truth of the Gospel. Conversely, the one who sought division reflected a lack of true connection to the Gospel. The Word of God acts as a sword (Hebrews 4:12), cutting through falsehood and exposing the intents of the heart. This discernment is crucial for the church, as Jesus Himself said that true followers will be known by their fruits, which include love for one another and adherence to His teachings.
